The past 200 years haven’t been kind to the American buffalo. Once the basis for the cultures and economies of Native Americans on the Great Plains, bison were nearly eradicated in the 19th century. Conservation efforts saved the animals from extinction, but they no longer roam freely on their old range. In a new documentary, the filmmaker Doug Hawes-Davis chronicles the history of human relations with the American bison. He and Western historian Dan Flores join Doug on Tuesday.

For the past 40 years western economies have splurged on debt, but it’s hardly a new phenomenon. Financial journalist Philip Coggan says that economic crises have a time-worn place in history.

Monday, he joins us to explain what these debt cycles can teach us about our current situation and how our attitudes might be about to change again.

When the Hindu philosopher Vatsayana wrote the Kamasutra some 2000 years ago, he said that he did so in a spirit of chastity and meditation – not for the sake of passion. So how is it that the treatise has become synonymous with sexual ecstasy and acrobatic positions? The writer James McConnachie joins us to tell the story of the Kamasutra’s journey from India to Victorian England and the role it has played in the West’s ongoing wars over sexuality and morality.

Utah's famed powder snow -- snow so great it typically covers local mountains well into the summer -- faces a dim prognosis. Several recent studies suggest spring snowpack in the Mountain West is dwindling, the result of a warming climate. If the predictions hold true, in the future the region will see less snow and more rain from fewer, more intense storms. A panel of guests joins Doug on Wednesday to talk about global warming's toll on the region's snowpack and the potential side effects.

There's geologic evidence of 6.5 and greater earthquakes violently shaking our region. Seismologists say it will happen again in Utah, though it's difficult to say when.

Inspired by the noise his family could never trace, Volk set out to explore the world of the paranormal. Doug talks to him about his research in the field of fringeology. (Rebroadcast)

Neil deGrasse Tyson, the director of the Hayden Planetarium and one of America's most vocal proponents of space exploration, is as fascinated with the depth and mysteries of outer space as he is with its proximity.

Tyson joins Doug on Tuesday to talk about his personal relationship with the cosmos and his crusade to get humanity back into space.
